Introduction
Imagine two people — Ravi, a 35-year-old software engineer, and his 75-year-old grandmother.
Ravi exercises regularly, doesn’t smoke or drink, and has no chronic disease. Yet, he feels constantly stressed, disconnected from family, and struggles with sleep. His grandmother, though diabetic, stays cheerful, socially active, and content.
So, who is truly healthy?
This simple question illustrates that health is more than just the absence of disease. It’s a balance of body, mind, and social connection — a concept beautifully captured by the World Health Organization (WHO).
Why WHO Defined Health
Before 1948, health was seen narrowly — as the absence of illness or disability. The creation of WHO brought a need for a universal definition that reflects the complete well-being of human beings. Hence, in 1948, WHO adopted its famous and still-influential definition.
WHO Definition of Health
“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” — World Health Organization, 1948
This definition revolutionized public health thinking by moving beyond disease control to well-being and quality of life.
Dimensions of Health
1. Physical Well-Being
Physical health refers to the efficient functioning of the body and its systems. A physically healthy person:
- Has no anatomical deformities or physiological dysfunctions
- Shows normal biochemical balance
- Can lead life normally and perform daily activities effectively
Examples: maintaining healthy body weight, regular exercise (150 minutes per week), balanced diet (with 45–60% carbs, 20–30% fats, 10–35% proteins), 7–8 hours of sleep, and routine health check-ups.
2. Psychological or Mental Well-Being
Mental well-being is the ability to think clearly, manage emotions, and cope with life’s challenges. It includes:
- Maintaining self-esteem and confidence
- Having a sense of purpose and control
- Managing stress through relaxation or mindfulness (10–15 minutes daily can improve focus and mood)
3. Social Well-Being
This dimension reflects a person’s ability to form healthy relationships, adapt to social roles, and contribute positively to society.
Healthy social engagement improves emotional resilience and longevity.
Disease and Infirmity — The Opposite of Health
A disease is a defined pathological condition caused by biological, genetic, or environmental factors, showing specific signs and symptoms.
Infirmity means weakness or loss of physical or mental strength, often due to aging or chronic illness.
Limitations of the WHO Definition
Although visionary, the 1948 WHO definition has some practical limitations:
- The word “complete” suggests perfection — rarely achievable in real life.
- It presents health as a fixed state, while health actually fluctuates daily.
- It overlooks spiritual, occupational, and ecological dimensions now known to affect well-being.
- It makes almost everyone “unhealthy,” making universal health targets unrealistic.
- The term “well-being” is subjective and varies across culture, age, and income levels.
Why the Definition Still Matters
Despite limitations, the WHO definition serves several key purposes:
- Guides nations in developing public health policies.
- Encourages individuals to maintain and monitor their own health.
- Reminds doctors that treatment should not stop at curing disease — it should aim for full well-being.
- Educates society about lifestyle choices, prevention, and holistic health.
Concept of Holistic Wellness
Holistic wellness is a dynamic and multidimensional process that aims for balance in all aspects of life.
While health refers to the state of being, wellness is about continuous growth and balance.
Health = Absence of disease
Wellness = Ongoing balance and optimization of life dimensions
Dimensions of Holistic Wellness
- Physical – exercise, nutrition, sleep, and preventive care
- Mental and Emotional – stress management, self-awareness, positive mindset
- Social – community interaction, family bonding, healthy communication
- Spiritual – sense of meaning, mindfulness, inner peace
- Occupational – job satisfaction, work–life balance
- Environmental – clean surroundings, sustainable living practices
Assessment Tools for Holistic Wellness
Several instruments measure holistic well-being scientifically:
- WHO-Quality of Life (WHOQOL) – Developed by WHO for cross-cultural quality-of-life assessment.
- Holistic Health Status Questionnaire (Chan et al., 2016) – Used in Hong Kong to assess physical, mental, emotional, and spiritual domains.
- Warwick Holistic Health Questionnaire (WHHQ-18) – Covers physical, emotional, social, and spiritual health dimensions in a concise format.
Holistic Concept of Health and Public Health
The holistic concept combines the biomedical, ecological, and psychosocial perspectives.
A healthy society is defined by:
“A sound mind in a sound body, in a sound family, in a sound environment.”
This approach recognizes that health is influenced by:
- Social and economic conditions
- Political and environmental factors
- Intersectoral collaboration — agriculture, education, housing, industry, communication, and more.
This integrated thinking gave rise to the One Health concept — linking human, animal, and environmental health for sustainable well-being.
Summary
- WHO (1948) defined health as a complete state of physical, mental, and social well-being, not merely absence of disease.
- The definition broadened medical understanding but remains idealistic and hard to quantify.
- Holistic wellness includes physical, mental, emotional, social, spiritual, occupational, and environmental dimensions.
- It views health as a dynamic process of maintaining balance, growth, and harmony in all areas of life.
- The One Health approach extends this philosophy to populations, animals, and ecosystems.
